2010 Chronicle Journal Multiple Choice Award Winner

After thirty years of practice I have made the decision to retire at the end of October 2013. Rest assured that your files will remain here at Superior Chiropractic and you will be provided with ongoing care through my very capable associates Drís Brimmell and Holmes each of whom have been in practice for over twenty years.

Patients have asked me which chiropractor they should see in my absence.

The answer to this question is not cut and dry, while both doctors use similar techniques to mine there are subtle differences from doctor to doctor. My suggestion is to book with either doctor for your first few appointments, give the doctor feedback as to what has worked for you in the past. Following these appointments you will decide if his adjustments met your expectations.

Keep in mind that it takes a series of treatments for any chiropractor to get to know your spine and how you adjust, be patient- remember that the adjustment is both an art and a science. If you were not completely satisfied with the adjusting technique of your first choice feel free to book a future appointment with the other doctor.

You are all aware that maintenance care is the key to good health and the prevention of future injuries. Carry on with your regular three week maintenance visits as you have in the past and before you know it you will become comfortable with your new doctor and his technique.

It has been my pleasure to provide you with chiropractic services over these thirty years and I trust that my associates will exceed your expectations for treatment in the foreseeable future.

Thank you,


P.S. I will be making personalized notes to the doctors regarding your file to expedite a smooth transition.
